ARTHUR I. POOLE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE WA'HL COIIAHY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE.

CALCULATING-MACHINE.

To all whom it may concern:

Be it known that I, ARTHUR F. POOLE, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification.

In my Patent No. 1,198,050, issued September 12, 1916, is disclosed a calculating machine. This machine is combined with a Remington typewriter, having the ordinary Gorin tabulator attachment, and is provided with a set of columnar totalizers and a universal totalizer. The columnar totalizers are mounted on a bar moved with the carriage. The universal totalizer is adapted to be connected to any of the columnar totalizers and will move in unison therewith during the insertion of a number; consequently the same number can be entered simultaneously in both a columnar and the universal totalizers. Both the columnar and universal totalizers are provided with tabulating means which bring them to the proper decimal place, prior to the insertion of any number. The tabulating means is actuated by the ordihary tabulating keys of the type writer. While all the power to bring the columnar totalizers to a required decimal place is furnished by the typewriter carriage spring, the power necessary to bring the universal totalizer to its position comes from the tabulating keys themselves.

My present invention is an improvement on the above described machine.

One of the objects of my invention is a power tabulated universal totalizer. To this end the universal totalizer is adapted to be connected to preferably a continuously running motor on the actuation of any tabulating key. The universal totalizer is thereupon tabulated to a position determined by talizer, thereby making their action more Speciflcationof Letters Patent.

easy, than in the machine described in my above mentioned application.

Another object of my invention is the particular constant aggregate motion linkage the carriage to return it.

Another objectof my invention is the linkage connecting the carriage return key with the clutch so that upon ,the carriage reaching a predetermined position it is disconnected from the source of power regardless of the position of the carriage return key at that time.

Another object of my invention is an elastic stop for said carriage .so that when it reaches the end of its return, it comes to rest withouta jar. Q

There are several other objects of this invention which will be explained in the body of the specification.

The invention is illustrated by the accompanying drawings forming part of the specification. There are a large number of parts in this machine which are in no wa different in operation from the machine escribed in the application above mentioned, and since these form no part of the present invention and would only tend to confuse the drawings, they have been accordingly omitted.

Figure 1 is a rear elevation of the machine. r

Fig. 2 is the left elevation of part of the machine. the particular key operated. The power is Fig. 3 is a top view of the rear of the machine.

Fig. 4 is the right elevation of the machine.

Fig. 5 is a detail of the particular form of clutch employed in connection with the carriage return.

Figs. 6 and 7 show details of the clutch used with the power tabulating device.

' Fig. 8 shows the constant a egate motion linkage in its normal position.

and connected to a source of power, preferably an electric motor. This motor is not shown in the drawings since it is well known and would simply tend to confuse them. The shaft 2 is so connected to the source of power as to turn in the direction of the arrow. Mounted on the shaft 2 is a,

clutch 2 shown in greater detail in Fig. 5. This clutch 2 consists of a socket 4 rigid with the shaft 2 and a slidably mounted cone 5. Embracing cone 5 is a ball bearing collar 6, pivoted at the points 3 to a fork 7,

rigidly mounted on a link 8. This link 8 is adapted to be moved by link 9 pivoted at.

28, by link 10 pivoted at 29 or by both of them acting simultaneously. Link 10 is connected through a lever 11 fulcrumed at 51 and twisted link 12 to the carriagereturn key 13 fulcrumed at 52. It is then evident that if we consider the pivot 28 sta tionary, a downward pressure on key 13' will cause engagement of'the cone 5 with socket 4, thus rigidly connecting cone 5 to the shaft 2.

On the cone 5 and rigidwith it is a spiral;

gear 14 engaging with a spiral gear 15 mounted on a shaft 16. At the upper end of shaft 16 is a spiral 17 in mesh with a.

spiral 18 rigid with a shaft 19, on the other end of which is a spur gear 20. Theshaft 19 and its associated gears l8 and 20 revolve in a suitable bearing 21mounted, on the framework 1. In mesh with the gear 20 is a rack 22 mounted on the typewriter carriage 25 by means of the stud screws 23. Immediately backof this rack 22, held by the same screws and separated from it by washers 41, is the regulartypewriter rack 42. Both of theseiracks are-mounted by means of the stud screws 23, on a swinging arm- 43 swinging about fulcrums -44- in the type-Q.- The spring "45 holds these racks 22 and 42v against a stop 47,

writer carriage 25.

which insures correct meshing of the rack 22 with the gear 20, and of the rack 42 with the gear 46, which is the regular spur gear of the typewriter. escapement 48. Slots '24 are cut in rack 22 so that it will have a oertain amount of longitudinal movement relative to the typewriter carriage 25. It is now evident that if the pivot 28 is stationary and the carriage return key 13 de- 'a link 26 fulcrumed to the pressed, thereby causing the gear 14 to 're I volve with the shaft 2, that motion will be transmitted 1 through shaft 16, gears'l'l, 18 and 20, to the rack 22, and as soon as this rack is moved to the left the length of the .slots 24, the typewriter carriage 25 willbe moved to the left also.

.- I will now describe the means for disen-- gaging the cone 5-and thereby stopping the carriage 25. The link 9 is fpivoted at 30 on ramework at 27,

and it will be observed that in their normal position the points 28, 30 and 27 are in a straight line. Pivoted to link 26 at a point.

31, is a link 32 whose upper end is attached to an arm v33 on a jack shaft 34. Rigid with this jack shaft 34 is a lever having a vertical arm 36 and a horizontal arm 35. Mounted on the carriage 25 is a screw 38 whose length is approximately equal to the maxlmum carriage travel. n this screw 38 is an adjustable nut 37 adapted to contact w1th the lever arm 36. Returning to the arm 35, it will be seen that it is in contact with an arm 39 fulcrumed at 49 and carrying the bearing of the tabulator-governor gear/40. It will be remembered that in the well known action of a typewriter tabulator when any tabulating key of the typewriter is actuated the governor gear 40 will engage with the typewriter rack 42,

thereby lifting it, from engagement with the escape'ment gear 46, and thus permitting the-carriage spring to move the carrlage to the right (as viewed from the rear rested by a tabulator stop. When this arm 39 is depressed by the arm 35 it will lift the racks 22 and 42 from engagement with their respective gears 20 and 46. At the sametime through the consequent depression of link 32, the link 26 is pressed downward thereby breaking the existing toggle 1 between fulcrum 27 and pivot 28, and

through the action of the link 9 on the link 8 disengaging the clutch 2 It will thus be seen that the lever fulcrumed at. 34 has two functions, one .by depressing the link 32 to disengage. the clutch 2 from the motor, the other by raising the governor gear 40 to lift the racks 22 and 42 from mesh with the gears 18 .and 46.

.The cycle of operation of the carriage return will then be as follows: Starting with "the carriage at some point where the nut'37 is not in contact with the arm 36, the key 13 is depressed. It will be observed that I since the points 27 30 and 28 are in "a straight line, the lever 8 will turn about the point 28 thereby causing engagemeent of the clutch 2 and transmitting the motion ofthe shaft 2 to the gear20. As soon as the rack 22 is moved the-length of the slots-24, the

carriage will move to the left (as viewed from the rear. See Fig. 1.) When nut'37,

109 of the machine, see Fig.1) until it is an which it will be remembered is rigid with moving it in acounter-clockwise direction,

two things occur. First the toggle which existed between the points 27 and 28 will be broken, the point 28 moved to the left thereby disengaging the clutch 2*. Second, under the influence of its momentum the carriage will continue to move to the left thereby further rotating arm 36, and the governor gear 46 will raise the racks 22 and 42 from their respective gears 20 and 46. This mo tion will he resisted by the spring 45 and the carriage spring until the momentum or the carriage is destroyed, then under the influence ofthe spring 45 and the carriage return spring 50, the carriage 25 will start to move to the right, and the arm 36 will move toward its normal position. As soon as the arm 36 is returned to the right far enough to allow the racks 22 and 4:2 to come into engagement with their respective gears 20 l6, the carriage will be stoppedby the escapement wheel 48 of the typewriter. it will he noted that as soon as the power is taken the carriage,- hy the disengagement oi the clutch 2*, it is moved against the tension of the spring 4:5 by its own momentum, and that when this momenturn is destro ed and it starts on its return to the right, it will he stopped at a definite point. Thus the carriage will be brought to rest without a jar.

It will be remembered that the rack 22 had longitudinal movement with reference to the carriage 25. This is for the purpose of feeding the paper at each return oil the typewriter carriage. In the rack 22 is a pin 53 engaging lever Eifulcrumed on the carriage 25 at 55. livoted to the lever 54 at 56 1s a rod 57. This rod 57 is connected by suitable linkage to the regular paper feeding mechanism. Since this mechanism forms no part of mv present invention, 1 have not shown it. it is obvious that each time the carriage is returned by the motor the rack 22 will he moved to the left until it comes to a defi its stop, which will he when the paper feet. pawl has advanced the paper,- then rack 22 will move carriage, until the clutch 2 is disengaged by the action of nut 37 on arm 66 as heforedescribed.

I will now describe the power tahulating mechanism for the universal totalizer. The universal totalizer 60 is mounted on a bar 61, sliding on two rods-62 (Figs. 1 and a). it is adapted to be connected to the columnar totalizers by a bar 63. As these parts and their functions have been fully described in my application above referred to, I shall not consider them further. As fully explained in this aforementioned application it is necessary when the tabulator carriage carrying" the columnar totalizers is tabulated, that the universal totalizer be tabulated also, since side a merit of the slidalole piece 78 to from that point until the number is inserted, the two totalizers move in unison. In my present invention 1 have provided a constant aggregate motion linkage to tabulate the universal totalizer. The general principle of this linkage is the same as that disclosed and fully ex 'lained in application Serial No. 697704, led May 16-, 1912, by Hyman Eli Goldberg. In that application the ordinary tabulator stops of the typewriter serve to locate the tahulatable totalizer by. a constant aggregate motion linkage. The same is true in my present invention but the constant aggregate motion linkage is difierently arranged, and the power for actuating the same comes from the motor instead of from the tahulator keys themselves. I

0n the shaft 2 (Figs. 1, 6 and 7) is a worm '64 meshing with a worm wheel 65 rigid with a shaft 66. Loosely mounted on this shaft 66 is a disk 67 carrying on one pawl 68, pivoted at 69, and on the other side an eccentric 70. A spring 71 tends normally to throw the point of the pawl 68 into engagement with a ratchet wheel 72. This ratchet wheel 72 is rigid with the shaft 66 and worm wheel 65, and since the motor is continuously moving, the ratchet 72 will be continuously moving in the direction of the arrow also. A slidalole piece 73 mounted in the frameworkl, has on it projections 74; and 7 5 in different planes. The pawl 66 has a cam surface 76 which by contact with the projection 74 holds the pawl 66 free from the ratchet wheel 72. piece 7 3 is displaced in the direction of the arrow (Fig. 6) until projection 74- is free from the cam 76, the spring 71 will throw the pawl 68 en agement with the ratchet 72. Consequent y d sk 67 on which pawl 68 is mounted will revolve with the 2. Ac-

suming the piece to remain in its displaced position during one revolution of disk 67, the cem'76 will come in contact with the projection 75 on the piece 73, and the pawl 68 will be withdrawn from the ratchet 72. The disk 67 will then stop. @n the replaceits normal position, the cam 76 will he released from the projection 75 and will immediately be engaged by projection 7 It is now evident that displacement of the slidahle piece 73, from its normal position, will cause the disk 67 to he turned by motor through one revolution and said disk will thereupon disconnect itseli from the motor and remain so recognized as the same in principle as the nonrepeatin clutch used inpunch presses. Fulcrumed at 77 (Figs. 1, 8 and 9) in the framework is a lever 78 having a slot which embraces the eccentric 70, and aroller 80 pivoted at 79. Consequently each displacement of the slidable piece 73 and consequent revolution of-the eccentric 70, will cause an up and down motion of the roller-80. Leaving for a moment this part of the mechanism Iwill now describe the constant aggregate motion linkage which tabulates the universal totalizer and is actuated by the roller 80. A shaft 81 is fulcrumed in the framework and carries on it in different planes two loosely mounted arms, 82 and 83. These arms are connected by two equal links 84 and 85 pivoted'at 86 and '87 respectively. Links 84 and 85 are joined in apivot 58 and also at this point is pivoted a cam 93. This cam 93 has three cam surfaces 88, 90 and 91. Cam surface 88 engages with a roller 89 rigid with the shaft 81. Cam surface 90 engages with the roller 80. Cam surface 91 engages with the shaft 81. The cam surface 91 is the width of the shaft 81 and ends in a semicircular surface about a point 92. The throw of the roller 80 is such that at the end. of its upstroke the chat 92 will bebrought into coincidence wit the center of the shaft 81. The distance from the shaft 81 to the center of the roller 89 is less than the vertical throw of the roller80. Consequently when the cam 93 is raised to its uppermost position thexcam surface '91 will embrace the roller 89 also. However, in this position the whole linkage has still freedom of rotation about the shaft 81, since the cam surface 90- against which the roller 89'is in contact at that time, is a semicircle about the point 92 and 92'is at that time in coincidence with the center of the shaft 81. in order to locate this linkage in, a definite position when the cam 98 is in its uppermost position, a locating bar 94is pivoted at 95 on the upper end of 82, and a locating bar 98 is pivoted at 97 on the upper end of 83. These bars are guided in suitable slots in the piece 59' rigid with the framework.

The bar 96 has a projection 98 on one end this rejection 98 extends into the plane of the ar 94, (Fig. 10). When the cam 93 is raised to its up ermost position, b means i of the roller 80, t e pivots 95 and 9 are in approximate alinement, (Fig. 9). The length of the locating bars 94 and. 96 are such that when the barsare in the position: shown in Fig. 9 the s ace between the ro-- ject'ion 98 and t e en of the bar. 94-is ust eqlxlal to the width of a tabulator stop, 113. 'l is is clearly shown in Fig. 10. It will be now evidentthat if any. tabulator stop is protruded and the slidable piece 73 actuated, thus causin an up and down motion of the roller 80, t e bars 94 and 96 will come in stop protru memes contact with the opposite sides of the protruded tabulator stop. Remembering that the linkage composed of'links 82, 83, 84 and 85 has freedom of motion about the shaft 81,-and when this linkage is in its operative position the space between the end of the' ar .94 and projection 98 is equal 'to the width of a tabulator stop, it will be seen that when operated this linkage will be located in a definite position according to the position of the tabulator stop. embraced by the bars 94 and 96. Now the cam 93 is then stop, and the roller 89 which it will be remembered is rigid with the shaft 81, will be brought toa definite position also. Therefore we have the following condition of afiairs: When a tabulator stop is protruded into the plane of the bar 94 and the projection 98, and the slidable piece 73 actuated, the roller 89 rigid with the shaft 81 Wlll be brought to some definite position de ending upon the particular tabulator'stop w ich has been protruded.

The connection between the roller 89 and the universal totalizer 60 is easily traced. It will "be remembered that the roller 89 is rigid with the shaft 81. Parallel to the shaft 81 is a shaft 99 fulcrumed .in the framework and having rigid with it, an arm 100. @n shaft 81 is an arm 98 equal in length'to the arm 100. Connecting arms 98 and 99 is a link 105 equal in length to the distance between the shafts81 and 99.

Consequently the framework, arms 98 and 199, and link 105 form a parallelogram linkage and the angular motion of shaft 99 will joining the centers of t e shaft 81 and the roller ,89. Since, when the locatin linkage is actuated, the angular motion of s aft 81 is equal to the angular motion of pivot 95 about said shaft,.the motion of the totalizer bar 61 will be equal in direction and amount to that of the pivot 95, which is to say that the totalizer 60 will take up the position determined by the particular stop embraced by the locator bar 95 and the projection 98. So then to recapitulate. If we have a tabulator ed and the slidable piece 73 actuated, the universal totalizer 60 will be brought to a position dependent upon the tabulator stop which has been protruded.

As I have stated the columnar andnniverpositions both totalizers are rigidly connected together by means of the bar 63, and move together in unison until after the insertion of the last digit of the required numher. They then are disconnected and remain so until the next succeeding tabulation. Since this linking together by means of the bar .63, moving inunison, and subsequent disconnecting of the universal totalizer from the columnar totalizer is exactly the same as that in my application above referred to, 1 shall not here describe them.

In Fig. 4 is shown the connection betwee the ordina F talhulator stops of the typewriter and the tabulator keys. Rod 106 has on its end a push button, not shown, and is one of the customary'set of tabulating keys, This rod is fastened to an individual lever 137 tulcrumed at 108. Lever 107 is connected by a rod 109 to tabulator stop 110 fulcrumed at 111 having an end 112 adapted to engage the ordinary tabulator lugs on the carriage and a portion 113 which is engaged by the bars 94: and 96. There is eneset of the above mentioned parts, 106, 107,109, 110, 112 and 113 for each tahulator key. it. universal bar 11% adapted to he moved by any of the levers 16 is also fulcrumed at 108 and is connected by a link 1155 to a rocker aiun rigid with the shaft 11'? iulcrunied in the frame work. Rigidwith the shaft 117 is a bent lever 116 fulcruined at 117. (Jensequently considering the chain which connects lever 116 to the tabulator lzey 106, motion or" the tab-ulster key 133 to the right (Fig. 4) will cause motion of the lever 116 to the left, Mounted on lever 116 is a stud A link 120 has one end a slot 121 sliding on the stud 119, and at the other end-is pivoted on a log 122 rigid with the slidahle piece 73.

. Actuation oi a tabulatcr therefore will produce actuation of slide-hie piece 73, which it he remembered releases the ta'ouiator clutch thus starting in action the chain mechanism which tahulates the universal totalizer.

W the columnar decimal carriage is tahulated by the use of the tahulator heys, it

is necessary to raise the 42 the escapeinent ear 46. Accordingly the bentv lever 116 is gointed by a rod 118 to the yoke 123 (Figs. 1 and 2) pivoted to the arm 39.. Eliot-ion oi the bent lever 116 therefore causes rotation of the arm 3%, about its fulcrum so and consequent disengagement or the rack 46 as previously described in this specification. The rod 118 is provided with a head 124, and telescopes into the yoke 123. it will be remembered that when the carri 25 is returned, the arm 39 is momentarily depressed. If the connection between the yoke 123 and the rod 118 were solid this might by actuation of the lever 116 release the tabulation clutch. This would be undesirable so the rod 118 and yoke 123 are constructed so that downward motion of the arm 38 will not afiect the lever 116.

Having now described my invention 1' shall call attention to some of its advantages. Taking up the carriage return portion first,

it will be noted that the elastic stop which serves to bring the carriage quietly to rest at the end of the carria e return, is the usual rack provided with ,t e carriage. As ordinarily constructed this rack is mounted on a swinging arm and held in engagement with the escapement gear by means of a spring. In my-constructlon this spring is utilized as the elastic stop against which the carriage is brought to rest on its return. This construction is simpler than providing an addi- 'tional piece to perform this function.

llt Wlll be noted that the link controlling the carriage return clutch is adapted to be acted on from two sources. First the manual key which serves to start the carriage on its return, and second, the lever 36 which is engaged by the carriage on its return to its predetermined position. These two parts just mentioned do not interfere with each other for it is obvious that upon the carriage returning to its predetermined position thus engaging the arm 36, the clutch will be disconnected regardless of the fact that the manual lrey 13 is still in a position to engage the clutch.

Attention is also called to the fact that in the chain of clutch disengaging linkage there is a toggle joint so a slight displacement of from its normal position, the clutch will cause the linkage to go through one cycle but no more in order to cause this cycle to repeat the tabnlator stop must first be restored to its normal position and then subsequently actuated, so that to each cycle of the tabulating key corresponds one cycle of the locating li kage.

in this specification l have used the adjectives columnar and universal to describe two kinds of totaliaers used in my inven- On the displacement of any tabulating key tion. By columnar totalizer 1 means a totalizer adapted to perform calculations on numbers arranged in vertical columns. By universal totalizer I mean a totalizer adapted to perform calculations on numbers arranged in any order, either vertical or horizontal. It will be observed also that 1n my present invention while the columnar totalizers can be tabulated in but one direction, namely, from right, toleft, the universal totalizer can be tabulated in either direction. The universal totalizer is usually tabulated from left to right but this 1s 'by step to determine the decimal place in which each digit is to be entered. ln in present invention this element is the ,tota izer itself. It is obvious that the totalizhr could be stationary and the master wheel move relatively thereto, or other means such as a movable stop operating on a set of trigggrs might be used to determine this decimal p ace.

it is obvious that my power tabulating mechanism could be applied to any of the constructions mentioned and l have therefore in the claims called the element which moves step by step to determine the decimal place in which each digit is entered,

the decimal carriage and I wish it to be accordingly so understood.

ll/lany changes can be made in the details of my hereindisclosed construction without de arting from the spirit of the invention. aving thus described my invention l. claun: a
